JOSEPH FREDRIOK YOUNG, OF MORRI STOWN, NEW JERSEY.

LEAF-TURNER.

To all whom it may concern:

Be it known that I, JOSEPH F. YOUNG, a citizen of the United States, anda resident of Morristown, in the county of Morris and State of NewJersey, have invented a new and Improved Leaf-Turner, of which thefollowing is a full, clear, and exact description.

This invention relates to turners for music and other folio leaves, andmore particularly to a music leaf turner in which is employed a manuallyoperable, swinging arm having a magnet adapted to contact with clipscarried by the leaves and fashioned from metal or other material capableof magnetic attraction, so that a leaf is turned as the arm is swungfrom one position to another, the arm being arranged gradually to becomedisengaged from the leaf as it swings, so that when the leaf itself hasbeen completely turned, the arm is free to return to the initialposition, without carrying the leaf back with it.

An object of the invention is to provide a simple and efficient music orother leaf turner which is inexpensive to manufacture, and in which theleaf turning arm is provided with a magnet adapted to engage metal clipscarried by the leaves, whereby the danger of tearing or otherwiseinjuring the leaves in turning them is obviated.

A further object of the invention is to provide a leaf turner by meansof which folio or other leaves can be turned in either direc tion, andin which the leaves can be remov ably but firmly held in position forthe operation of the turner.

The invention consists in the construction and combination of parts tobe more fully described hereinafter, and particularly set forth in theclaims.

Reference is to be had to the accompanying d awings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which Figure l is aperspective view showing my invention as applied to a piano; Fig. 2 anenlarged front elevation of the lower portion of the device, showingcertain of the parts in different positions in dotted outline; Fig. 3 isa longitudinal section of the leaf turner; Fig. t is an enlarged rearview of the lower central part of the stand shown in Figs. 1 and 2. Fig.5 is a front elevation showing one form of the clips which areSpecification of Letters Patent.

attached to the leaves and are capable of magnetic attraction; Fig. 6 isan enlarged transverse section on the line 6-6 of Fig. 3; and Fig. 7 isan enlarged transverse sec tion of the means for holding the leaves inposition, showing certain of the parts in different positions in dottedoutline.

Before proceeding to a more detailed explanation of my invention, itshould be clearly understood that while I have shown, for example, amusic leaf turner adapted to be removably used in connection with apiano or other musical instrun'ient, the invention can also be employedfor other purposes, for instance, as an attachment for reading purposes,wherein it serves to turn the leaves of a book or the like. Any suitableform of clip can be removahly applied to the leaves to be turned,provided the clip is capable of magnetic attraction, so that the magnetcarried by the swinging leafturning arm can engage the clip and hold itwith sufficient strength to permit the leaf to follow the movement ofthe arm. The arm is so arranged that as it swings from one position toanother it moves downward, and thus gradually the magnet slides out ofengagement with the clip; consequently, when the leaf has reached itsturned position, the magnet has moved out of contact with the clip, andthe arm is free to return without carrying the leaf back. The arm isadjustable and can be arranged to turn leaves in either direction; thatis, from right to left or from left to right, in each instance, afterbeing suitably adjusted, operating to release the leaf automatically, bythe time it has attained the turned position.

leferring more particularly to the drawings, I employ a frame,consisting of a base 10 fashioned from wood or other suitable materialand having feet 11 by means of which the frame can be held in a properupright position, as is shown for example in Fig. 1, upon the musicboardof a piano, or upon any other suitable support. The frame has posts 12consisting of metal rods or the like, and preferably slanted backward toa slight degree so that the folios or leaves :an restproperly thereupon.A cross-bar 13 mounted at the upper ends of the posts, has theextremities projecting laterally therebeyond. Upon the projectingextremities of the cross-bar 13 are sleeves 14: of rubber or otherresilient material, to obviate the danger of injuring the piano or othersupport. Near the center, the base carries an upright holder 15,consisting preferably of an angle of metal having at the bottom alaterally disposed flange 16 secured to the base by means of a screw 17or the like. At the upper end, the holder has a second flange 18. Aclamping bar 19 is pivoted between the flanges l6 and 18 and ispreferably of semi-circular section, having the rounded side disposednormally at the inside' of the angle iron. A locking rod 20 is securedto the clamping bar 19, for example, by having a laterally disposed endinserted in an opening of the clamping bar, and serves to hold thelatter in a plurality of positions by means of a laterally disposedextremity 21 which can be positioned in openings 22 of the base. Theholder 15 and the clamping bar 19 constitute the means for positioningthe leaves. The latter are held at the folds, as is shown most clearlyin F 7, being clamped between the holder and the clamping bar, thusleaving the leaves free to l e turned in either direction. To releasethe leaves it is merely necessary to lift the locking rod out ofengagement with one of the openings 22 and to swing the clamping baraside, as is indicated in dotted outline in Fig. 7.

The base 10 has a transverse opening un derneath the leafholdin means,and has pivotally mounted therein a pintle 23 which extends beyond thebase at t ie front and back thereof. in arm 2-ft is pivotally securedatthe forwardly proj eoting end of the pintle, by means of a laterallydisposed eX- tremity 25 arranged in a transverse opening of the pintle,and held in position by a head 27. The free end 28 of the armis-bifurcated and has secured between the sides by means of a rivet 29or the like, a magnet 30 which may be of any suitable form, for example,as shown, of the ordinary horseshoe type. An operating member 31 isarranged underneath the base and has an upwardly disposed portion 32arranged in a transverse opening at the rearwardly projecting end of thepintle. 'i he upwardly disposed portion 32 extends above the pintle andhas mounted thereon a helical spring The latter has one end secured tothe portion 32 of the operating member and the other end fastened bymeans of a pin 35, to the pintle. At the free end, the operating memberis laterally disposed to form a handle 36 which may be of any formadapted to be grasped by the hand. An offsetbracket 37 is rigidlycarried by the operating member and engages a stud 38 of the swingingarm. whereby the operating member controls the arm.

The base 10 has a cut-away portion 39 which permits the free movement ofthe operating member 31. Cushions 40 of rubber or other suitablematerial, are carried by the parts and serve to protect the base fromthe impact of the magnet thereagainst, as is shown most clearly in Fig.2.

The pintle 23, at the rear end, and adjacent to the back of the base 10,has an annular groove i1 which receives the opposite sides of avbifurcated spring keeper The latter is fashioned from resilient wire orother suitable material bent upon itself to form a V-shaped memberhaving at the extremities, eyes i3 formed to receive screws aid or thelike to hold the keeper in position. At the bend, a further screw +15employed to mount the keeper upon the base. The keeper friction-allyengages the pintle and to hold the same in any one of a plurality ofpositions, though permitting it to be manually or otherwise adjustedinto the different positions for a purpose which will appear moreclearly hereinafter.

It is of course necessary to secure to each of the leaves to be turned,a part or member capable of magnetic attraction so that the magnet cantemporarily attach to the leaf. Any desired attachment can be employed:as shown, for example, in Fig. a bar at; of metal, pasted or otherwisesecured in place, can be used. I prefer however, to employ a clip 4- 7fashioned from wire or the like and having separable resilient sidesbetween which the edge of the leaf is received, and provided, further,with crossbars 18 adapted for engagement with the magnet.

The operation of the leaf turner as follows: The folio fr consisting ofany desired number of leaves, is placed between the holder and theclamping bar, and is thus positioned for use. each of its leaves havingbeen previously provided with a clip 47 or other similar attachment..Vhen the leaves are to be turned from the right to the left, as isshown in Fig. 1, the swinging arm and the operating member are arrangedas shown in Fig. 2, with the pintle 2?) turned so that a stop 1-9 rigidwith the pintle engages the lower side of the spring keeper. In otherwords, the arrangement such that as the arm swings from right to left itgradually moves downward as is indicated in dotted outline in Fig.Consequently, in turning a leaf from right to left, the magnet isgradually disengaged from the clip and when the leaf reaches the turnedposition the magnet is free to return without carrying the leaf backwith it. he spring 31 serves to return the swinging arm. through theoperating member, to a normal position at the right hand side of theWhen it is desired to turn the leaves from lef to right, the pintle isrotated until the stop 49 engages the upper side of the keeper 42, thatis, until the magnet when at the left side of the base, is in itshighest position. Consequently,

when the arm is swung from left to right, the magnet gradually descendsso that when the leaf has reached the right-hand side of the frame themagnet is disengaged from the same.

If so desired, the cross-bar 13 may be weighted, to assist in securelypositioning the device against the piano or other support.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent 1.
